SHEET 3 UP 3 ATTORNEY CORD HANGERS FOR HOIST This invention relates to a combination mobile carrier and hanger for various uses such as when supplying electric current, through an insulated supply cord, to a movable electric apparatus which may be mounted on a hoist, or a small type crane, or the like, characterized in that the supply cord and a stretched messenger or support line can respectively and easily be passed through and removed from different parts of the hanger and in such a manner that the supply cord can be suspended flexibly.

This general prior art kind of cord hanger usually has a bracket in which a carrier roller and a guide roller are fixed by means of separate axles, but in such a, non-, separable manner that in passingthrough a messenger line between the said carrier roller and the guide roller, the messenger line must be threaded through from its one end. In other words, these prior known cord hangers cannot be used in association with a support or messenger line which has already been strung up. Moreover, a cord supporting member to hold a flexible supply conduit or cord usually comprises two opposite metal fittings in Q. (omega) shape, which heretofore have generally required coupling together by means of a bolt and a nut. Accordingly, it is particularly difficult to assemble such metal fittings by bolt and nut at high places, such as on overhead cable or rod supports.

This invention has for its object to eliminate the above-mentioned disadvantages of the cord hanger of known types.

Descriptions will be made below of a flexible cord hanger according to the present invention, with reference to the attached drawings, in which:

FIG. 1 is a diagram illustrating the condition unde which hangers according to the present invention are used in conjunction with an overhead hoist.

FIG. 2 is a front view, showing the condition under which the flexible supply cord hanger of the present invention is used.

FIGS. 3A and 3B show respectively cross-sectional views of different embodiments of the composite bracket part.

FIGS. 4A and 4B show respectively cross-sectional views of different embodiments of the cord supporting member of the hanger, also of composite form.

FIG. 5 shows a perspective view of the various disassembled parts of the hanger brackets and the cord supporting segments or members, and

FIG. 6 is a cross-sectional view of the bracket part shown in FIG. 3A but with which is engaged a cord supporting member of still a different type than that shown in FIGS. 4A and 4B.

In the drawings, numeral 1 denotes an upper bracket of the mobile carrier, which bracket 1 is formed in inverted-U shape. Rotatably supported in this upper bracket 1 by means of an axle 4, is a carrier roller 2. Claws or shoulder portions 1a, 1a are formed near the bottom outer surface of the upper bracket 1. Numeral 3 denotes a lower bracket of U-shape, with its opening facing upwardly. Claws 3a, 3a are formed at the upper inner surface of this lower bracket 3. It is so designed that said claws 341,311 and claws la, la of the upper bracket complementally engage with each other and thus the upper bracket 1 and the lower bracket '3 are detachably connected. Loosely and rotatably supported in the lower bracket 3 by means of a pin axle 5 is a guide roller 6. When the upper bracket 1 and the lower bracket 3 are interconnected by engagement of complemental claws 1a and claws 3a it can be readily assembled around, a messenger line 12 (or a stretched rope) which is held between peripheral grooves of the respective carrier roller 2 and the guide roller 6. In other words, the messenger line is embraced by a recessed groove formed between rollers 2 and 6 so that composite bracket means A comprising the upper bracket 1 and the lower bracket 3 so asvnot to detach from the messenger line. 'At the underside of the lower bracket 3, a composite cord supporting means B is suspended by means of a pin 7 made separately or through the medium of a connecting pin 7 which is made integral with the lower bracket 3, or with the cord supporting means B. As indicated by FIGS. 4A and 4B, the composite cord supporting means B comprises a main body 8 of substantially inverted-L shape, having a horizontal upper piece or short leg and a longer perpendicular leg or piece, and a cord gripper segment 9. The afore-mentioned connecting pin 7 is put through a hole formed in the upper piece 8a of the main body 8, whereby the cord supporting means B is connected in a swivel-like movable manner with the bracket means A. The perpendicular piece 8b is curved in a lower or medial part so that a curved part 8d may fit the arcuate or contoured surface of a flexible. cord. Adjacent the upper and the lower parts of the curved portion 8d, there are provided engagement holes 8c, 8c. The cord gripper 9 is detachably engaged with the main body 8 of the cord supporting member to hold a flexible element or cord 11 between the main body 8 and the cord gripper 9. The cord gripper 9 is preferably also formed complemental to portion 8d in substantially C- shape and its curved portion 9d at the center corresponds to the curved portion 8d of the main body 8. Thus, the flexible cord is supported between the curved portions 8d and 9d. The cord presser 9 further includes a pair of spaced leg-portions respectively having sawtoothed arms or engagement claws 9a, 9a, which are inserted-in corresponding body engagement holes 80, 8c whose respective adjacently disposed upper and lower wall portions are complementally'slanted, or beveled, to thereby connect the main body 8 with the cord gripper 9 in a unitary assembly or body. In this case, a plurality of engagement teeth or claws 9a are provided, as shown by FIG. 5, to make the embracing force constant by adjusting the extent of which the serrated arms or engagement claws are to be inserted in the engagement hole according to various diameters of the flexible cords. The distance between transversely projecting serrated arms 90 and 9a is made slightly larger than that between engagement holes and 80 so that when said arms are inserted in engagement holes, firm engagement is effected due to an inherent elasticity of said arms in the outward direction, thereby engaging the main body.8 with the cord gripper 9 as a unit.

The bracket means A comprising the upper bracket 1 and the lower bracket 3, the cord supporting means B and other parts should preferably be made of either metal or synthetic resin having suitable elasticity so as to ensure firm engagement of the respective parts.

In cases where a flexible cord 11 is to be suspended by the bracket of the above-mentioned construction, engagement claws of the upper bracket 1 and the lower ing means B. 1

bracket 3 are disengaged and reapplied to each other around the messenger line 12, with the line 12 held between the carrier roller 2 and the guide roller 6. Then, while both brackets are being engaged with each other as a unit'by means of the'respective claws, a rubber cushioning piece in generally cylindrical or drum shape for protection of the flexible cord 11 is applied thereon by means of a longitudinal slit, and is then assembled with'the main body of the cord supporting member, 8, being engaged by the cord gripper 9 so as to support the cord 11. In cases where two or more flexible cords are used, another or further cord supporting means B, made either integrally or separately, may be connected to and below the first cord support- FIG. 1 shows the state in which the cord hanger according to the present invention is used. The messenger line 12 and the flexible cord 11 connected to the hoist are stretched'along a girder 13, whereby the bracket A is free to travel as it is suspended by the messenger line and in turn supports the flexible cord 11.

The afore-mentioned is an explanation of the combination of the hanger A shown by FIG. 3A'and the cord supporting means B shown by FIG. 4A. Different embodiments of the bracket part and the cord supporting member are shown in FIG. 38, FIG. 4B and FIG. 6. Referring to the bracket part shown by FIG. 3B, the engagement of the upper bracket 1 with the lower bracket 3 is effected in the following way:

Engagement pieces or link-like portions lb and 3b are provided with hinged barrel portions which are pivotally secured by a pin P so that they act as if they were a hinge. The formerly described type of engagement claws la and 3a are provided opposite the hinge so that the upper bracket and the lower bracket may be opened and closed without need for completely separating them, but the other parts thereof are the same as in the case of FIG. 3A. A further embodiment of cord supporting means B is shown by FIG. 4B and comprises an engagement piece 8x at the lower end of the main-body 8 and another engagement piece 9x at the lower end of the cord gripper body. These engagement pieces 8x and 9x complementally engage with each other. The engagement of the main body 8 with the cord gripper 9 is of the open-close typeas mentioned above, i.e., it has one saw-toothed leg for selective insertion into the complemental engagement hole of the main body 8. Still another cord supporting means 8'' is shown in FIG. 6 is an embodiment in which the main body 8 and the cord gripper 9 are inter-engaged in the fashion of hinge. The bracket parts or means shown in FIGS. 3A and 38 could be used in combination with any of cord supporting members or means shown in FIGS. 4A and 4B.

The foregoing is a description of how to suspend the flexible cord 11. In FIG. 1, if numeral 12 depicted a stretched support cable or rope and numeral 11 depicted an air pipe to supply compressed air, they could be used in conjunction with an air operating apparatus.

According to the present invention, the upper bracket and the lower bracket can attach to a messenger line or a stretched rope by simplified means of only engaging the opposing engagement claws. This dispenses with the trouble of bolting, etc. and makes it quite easy to assemble at a high place. Moreover,

because the bracket means A is connected with the rotatable swivelly attached flexible cord-supporting means B, it can move freely in proportion or relative to the movement of the flexible cord. Further, because holding of the flexible cord is effected by an inter-engagement of saw tooth claws of the cord gripper 9 with holes of the main body 8, such holding can bedone with ease and attachment of flexible element or cord is made easy.
